12.2.3 Analog Input Modules
The analog input modules provide 16-bit measured data and 8 control/status bits
per channel.
EtherNet/IP does not use the 8 control/status bits, i.e., it does not access or
evaluate them.
Therefore, only the 16-bit measured values for each channel are in Intel format
and are mapped by word in the input process image for the fieldbus
coupler/controller with EtherNet/IP.
If digital input modules are in the node, the analog input data is mapped first into
the input process image, followed by the digital input data.
Each input channel occupies one instance in the “Analog Input Point Object”
(Class 0x67).
Information for the control/status byte development
Please refer to the corresponding description of the I/O modules for the structure
of the control/status bytes. You can find a manual with the relevant I/O module
